While waiting, I would throughly clean all the oil off the motor. Remove tank and whatever else to gain access. Once clean, determine exactly where the source of the leak is.

Still can't be sure? Run the motor and watch for the leak on the clean motor. This should make it obvious if the leak is not too subtle.

Make certain the crankcase vent hoses or other crankcase vents are not pinched or blocked. May be more than one. This is a common cause of oil leaks.

Next. Check torque values on valve cover or cyl. head or what ever part you think is leaking. Try loosening all the fasteners, removing part, cleaning, then examine gasket for damage, a cut, pinched or misalignment.

Sometimes a good cleaning and careful re-install and re-torque will do the trick. Make sure bolts are tightened in sequence, criss cross pattern. Tighten in three stages, keeping everything even. (IE : 5 ft. lbs. then 10 ft. lbs. then
final torque, 15 ft. lbs. )

As a temp fix, sometimes a good automotive silicone caulk/sealer will stop an oil leak if applied carefully and correctly.

This solution is commonly used on older DR650's that are plagued with leaking cylinder base gaskets. A good caulk around the base stops the leak.

Good luck.

BTW, any good auto mech can fix this, make a gasket or any number of other solutions. No BMW dealer needed other than for parts. But gaskets can
be made or improvised usually. Rubber O ring type will be harder but doable. You can buy rubber O ring type gasket off a roll and cut to length. (good truck or auto parts supply) Use a flexible sealer where two ends join. Been there, done that.

If it is a paper gasket it would be possible to make one, just use some paper/card and some gasket seal. It may be a O ring type seal which has broken and they can be cleaned and rejoined with super glue. Failing that you could try some silicone gasket.

Take of the 8 bolts (with rubber bushes) and clean everything. A thin layer of silicone on the gasket will probably help.
